WI-SUN DCU enclosure for AMI with a sub rack {a DCU box with a subrack}

The present invention relates to a WI-SUN type DCU enclosure for an AMI equipped with a sub rack, and more particularly, to a DCU enclosure having a sub rack detachably installed inside the DCU enclosure, And more particularly to a WI-SUN type DCU enclosure for AMI equipped with a sub rack that can be easily repaired if each configuration is damaged.

The core of remote meter reading is electronic watt-hour meter, chip, and bidirectional communication. The technology development has been completed through R & D from early 80's and pilot project from 2004, and full-scale business is planned from 2012.

Here, the conventional mechanical instrument is replaced with an electronic instrument for the low pressure customer remote meter reading, and the electronic instrument transmits the meter data every cycle. At this time, the data is collected in a data concentrator (DCU) (Hybrid Fiber Cable) network to the upper server and bidirectional communication is carried out.

In addition, the intelligent power grid is a global trend that aims to advance the electric power business, and by transferring meter data by adding IT to the existing grid, and by bi-directional communication between the customer and the electric power company, it induces a revolution in the electric power business.

Currently, the government and electric power companies are aiming to become a global leading country in the field of intelligent power grid. By 2020, they will announce concrete realization plans and provide meter data by installing an electronic wattmeter for 18 million customers, and conduct bidirectional communication through wired and wireless Is expanding its remote meter reading system.

This means significant technological environment change. It means completion of AMI (Advanced Metering Infrastructure) centered on metering data and interactive communication. Based on this, it is possible to construct a meter data management system, which is a core goal of intelligent power grid, And efficiency can be improved.

In such a remote meter reading system, the role of a data concentrator (DCU) is important. Such a data concentrator (DCU) is installed on a pole or the like. There is a problem that it is not easy to repair the entire printed circuit board since it is necessary to check the entire PCB board.

In addition, when the data concentrator is installed on the electric pole, there is a problem that it is difficult to securely fix the portion where the electric pole concentrator is contacted.
